Using LINQ’s aggregate

A long time ago, on a far away galaxy, every time we fell need to aggregate let’s say a string of IPs comma separated, we had to write something like:

                string ips = String.Empty;

                foreach (var address in ipInterfaceProperties.UnicastAddresses)
                {
                    if (ips != String.Empty)
                    {
                        ips += "; ";
                    }

                    ips += address.Address.ToString();
                }

With a more functional approach we can now write it like:

                string ips = 
                        ipInterfaceProperties.UnicastAddresses
                        .Select(p => p.Address.ToString())
                        .Aggregate((acumulator, next) => acumulator + "; " + next);

Please, God, don’t ever throw me into a non LINQ project anymore, please!…
